It seems relevant that the categories healthcare, housing, and higher education are not paid by wages/cash but rather through various means of financing (in the form of insurance for healthcare). (In addition to not being outsourcable).

New cars not increasing looks strange but that might be a US phenomena, where most cars might be imported and the median car have "shrunk" in size over the period.

It highly depends on what your definition of a price increase is. The cars people actually buy have definitely become more expensive with more and more people choosing to buy SUVs.

The sedan hasn't become more expensive, but people don't feel safe driving them anymore between all the large SUVs, this pushing more people towards buying more expensive cars.
